Course Description
Xmas Trees and Well Heads are critical parts of any Oil & Gas Well. They control the pressures in the Casings and Production Tubing, regulate the production rates and are very important barriers in case of leaks.
This intensive Xmas Trees and Well Heads Operation and Testing training course will highlight all components of a Well Head and of a Xmas Tree and the installation sequence . Casing and tubing seals (monitoring and leak repairs) different sauses of SAP pressures and hazards originated by faulty wellheads (and their mitigation) will also be discussed.
Course Objectives
- Develop the knowledge relationship between surface (Well Heads) and downhole.
- Investigate leaks and identify cause of leak
- Determine Tubing pressures (based on depth of perfs, density of fluid and BHFP).
- Investigate SAP pressures based on well pressure monitoring using 2 and 3 pen recorders.
- Explain influence of corrosion models on MAASP pressures and on Well Life Cycle
